Timing oscillations · Year 12 · 1 mark

  1. A stopwatch reading has an uncertainty of ± 0.2 s. A student times 20 oscillations of period about 0.8 s. What is the percentage uncertainty in the period?
    (1)

Show worked solutionHide worked solution
  1. The time measured is about 16 s, so the percentage uncertainty is 0.2 ÷ 16 × 100. Dividing by 20 does not change the percentage.C: 1.25%
